Exhaust donut gone!!!

Well, just by going by the 'ol butt dyno the car seems to be more eager to rev. Also, the exhaust note is louder than it was before. I am running the stock exhaust minus the back muffler. Sounds like the old MG's or Fiats. Very european. Well worth the $2.56 for the new swivel ring. My .02...

Yeah, the restrictor in the stock ring blocks nearly half of the available area. Good riddance!
If you can find a cam from an 8V GTI/GLI or a Digifant A2 (has a "G" on the cam vs. the plain hydraulic cam which has an "A" that looks like a triangle) it will help it rev more freely at higher rpm's and can be very inexpensive. Makes it really sweet from 4-5 grand but still pulls nicely off the line.

Yes, Vee Dubb, the bigger-valve head is better. I just had one of the stock hydraulic factory GTI cams laying around and it will work better than the stock Fox cam until I get around to putting on a solid lifter GTI head (like vwcabby mentioned). Plus, the cam swap is easy and I was changing the cam cover gasket, anyway. I've got a Dasher ex. manifold to go with the GTI head and if I can round up some 10:1 pistons they'll go in at the same time.
